The openable-closable folding type moon pool baffle device, disclosed by the invention, is ingenious in structure, can effectively inhibit vibration of waves in the climb direction and the vertical direction in the moon pool, reduces the influence of waves on the internal structure of the moon pool, relieves impact of sea water to the platform, and ensures that the platform can work normally and stably under various working conditions.
Description
Technical field
The present invention relates to one can the collapsible moon pool damper gear of opening and closing, belongs to Naval Architecture and Ocean Engineering technical field.
Background technology
Along with the mankind are to the increase in demand of the petroleum gas energy, the exploitation of land resources can not meet existing oil supply, offshore oil exploration is very urgent with exploitation, various novel marine settings continues to bring out under the new situation at this, drilling ship and all kinds of drilling platform as the main product of offshore drilling equipment also in constantly development and innovation.On drilling ship and all kinds of drilling platform, all can be furnished with this structure of moon pool.Moon pool is generally positioned in the middle part of platform, from the straight-through bottom of upper deck.Various drill outfit and pipeline from moon pool by carrying out exploitation work.Because moon pool directly contacts with seawater, climbing of whirlpool and wave after contact with sea water to moon pool pool wall, can be produced.Under the combined action of wind, ripple, stream, seawater also can form " rocking " motion of vertical " piston " motion and horizontal direction.Tremendous influence is brought to ocean operation and life on ordinary days.
In order to tackle these adverse effects of moon pool, it is general that in moon pool structure, add etcetera and add in moon pool can the shifting board of open and close type, due to moon pool limited space, add the effective operation space that etcetera will certainly reduce moon pool, accrete existence also can have a certain impact to the layout of drill outfit.
For moon pool structure, when works navigates by water, first incoming flow meets with the forward position of moon pool, forms whirlpool, whirlpool constantly expands along water (flow) direction, along place after reaching moon pool, and pool wall collision, cause climbing of wave, liquid level in moon pool is due to the effect of disturbance, also can produce violent oscillation action, therefore, design a kind of wave that can effectively reduce and to climb and the device of wave oscillations is very important.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides one can the collapsible moon pool damper gear of opening and closing, can open and close initiatively baffle plate, thus avoid wave on the impact of moon pool by actuating device.
Technical scheme: for achieving the above object, of the present invention can the collapsible moon pool damper gear of opening and closing, comprise initiatively baffle plate, driven baffle plate and actuating device, described active baffle plate one end is hinged on crank, the other end and driven baffle plate one end hinged, described active baffle plate near one end of crank and actuating device hinged, actuating device and crank are fixed on works, works is provided with guide rail, driven baffle plate is provided with the guide wheel along guide rail movement; When actuating device drives active baffle plate around crank, the guide wheel of driven baffle plate is along guide rail movement.
As preferably, described actuating device comprises oil cylinder and piston, and oil cylinder is fixed on works, piston one end and initiatively panel hinge, when piston stretches, drive initiatively baffle plate around crank.
As preferably, described piston is by the first anchor shaft and initiatively panel hinge, and oil cylinder is connected with works by the first rotating shaft.
As preferably, described crank comprises spectacle eye, the second rotating shaft and the second anchor shaft, described spectacle eye one end is hinged on lower installation board by the second rotating shaft, the spectacle eye other end is fixedly connected with upper mounting plate by the second anchor shaft, upper mounting plate is fixedly connected with active baffle plate, lower installation board is fixedly connected with works, and spectacle eye comparatively common hinge rotates more flexible, also effectively can prevent stressed concentrating simultaneously.
Beneficial effect: of the present invention can the collapsible moon pool damper gear of opening and closing, structure is ingenious, effectively can suppress climbing of wave in moon pool, reduces wave to the impact of moon pool inner structure, alleviate seawater to impact platform, ensure the device of platform normal table work under various operating mode.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figures 1 to 6, of the present invention can the collapsible moon pool damper gear of opening and closing, comprise initiatively baffle plate 1, driven baffle plate 2 and actuating device, described active baffle plate 1 one end is hinged on crank 3, the other end is hinged by hinge 5 and driven baffle plate 2 one end, described active baffle plate 1 near one end of crank 3 and actuating device hinged, actuating device and crank 3 are fixed on works, works is provided with guide rail 7, driven baffle plate 2 is provided with the guide wheel 6 moved along guide rail 7; When actuating device drives active baffle plate 1 flexing handle 3 to rotate, the guide wheel 6 of driven baffle plate 2 moves along guide rail 7.
In the present invention, described actuating device comprises oil cylinder 4 and piston, and oil cylinder 4 is fixed on works, and piston 41 one end, with initiatively baffle plate 1 is hinged, when piston 41 stretches, drives initiatively baffle plate 1 flexing handle 3 to rotate.Described piston 41 is fixedly connected with active baffle plate 1 by the first anchor shaft 42, and oil cylinder 4 is connected with works by the first rotating shaft 43.
In the present invention, described crank 3 comprises spectacle eye 31, second rotating shaft 32 and the second anchor shaft 33, described spectacle eye 31 one end is hinged on lower installation board 35 by the second rotating shaft 32, spectacle eye 31 other end is fixedly connected with upper mounting plate 34 by the second anchor shaft 33, upper mounting plate 34 is fixedly connected with active baffle plate 1, and lower installation board 35 is fixedly connected with works.First rotating shaft 43 and the second rotating shaft 32 diameter get 15 ~ 20cm, and the first anchor shaft 42 and the second anchor shaft 33 diameter get 12 ~ 15cm, and the first anchor shaft 42 and the second anchor shaft 33 are provided with sealing arrangement and axle sleeve.
